Delta ALB95 fault code meaning
Delta / ALB95
Series: ASDA-H3
Second power supply module - External regenerative resistor open or regenerative transistor short circuit
servo drive
Meaning:
Possible causes
- The regenerative resistor connected to a power supply module rated 45 kW or below is open, or the regenerative transistor has a short circuit.
- The regenerative resistor capacity setting (P8.088) is greater than 0, but no regenerative resistor is connected in the actual wiring.
- Regenerative energy processing circuit error.
